摘要:
针对现阶段避雷器试验方法的不足,提出了基于宽带脉冲电流法的避雷器局部放电测量方法,在对其测试方法、测试系统进行介绍的基础上分析了避雷器固定金属间隙悬浮放电、内部受潮放电以及表面爬电三种典型缺陷下的局部放电图谱特征,包括了幅值-相位图、原始脉冲波形图以及信号频谱图。最后通过两起案例的应用,验证该测试方法的现场实用性。
Abstract:
In consideration of the shortage of current testing methods on arresters, the partial charge test method for arresters based on wide-band pulse current method is proposed. On the basis of introduction of proposed test method and testing system, the features of partial discharge graphs under three typical types of defects; namely, the discharge suspended at gap between the fixed metal, the discharge due to interior damping and the creepage on the surface is analyzed, including the amplitude-phase, the original pulse waveform and the signal spectrum graphs. Finally the practicability of proposed test method is verified by two relevant case applications.
